__cacheline_group_begin(), unfortunately, doesn't align the group anyhow. If it is wanted, then you need to do something like __cacheline_group_begin(grp) __aligned(ALIGN) which isn't really convenient nor compact. Add the _aligned() counterparts to align the groups automatically to either the specified alignment (optional) or ``SMP_CACHE_BYTES``. Note that the actual struct layout will then be (on x64 with 64-byte CL): struct x { u32 y; // offset 0, size 4, padding 56 __cacheline_group_begin__grp; // offset 64, size 0 u32 z; // offset 64, size 4, padding 4 __cacheline_group_end__grp; // offset 72, size 0 __cacheline_group_pad__grp; // offset 72, size 0, padding 56 u32 w; // offset 128 }; The end marker is aligned to long, so that you can assert the struct size more strictly, but the offset of the next field in the structure will be aligned to the group alignment, so that the next field won't fall into the group it's not intended to. Add __LARGEST_ALIGN definition and LARGEST_ALIGN() macro. __LARGEST_ALIGN is the value to which the compilers align fields when __aligned_largest is specified. Sometimes, it might be needed to get this value outside of variable definitions. LARGEST_ALIGN() is macro which just aligns a value to __LARGEST_ALIGN. Also add SMP_CACHE_ALIGN(), similar to L1_CACHE_ALIGN(), but using ``SMP_CACHE_BYTES`` instead of ``L1_CACHE_BYTES`` as the former also accounts L2, needed in some cases.

Bartosz Golaszewski says: ==================== net: phy: aquantia: enable support for aqr115c This series addesses two issues with the aqr115c PHY on Qualcomm sa8775p-ride-r3 board and adds support for this PHY to the aquantia driver. While the manufacturer calls the 2.5G PHY mode OCSGMII, we reuse the existing 2500BASEX mode in the kernel to avoid extending the uAPI. It took me a while to resend because I noticed an issue with the PHY coming out of suspend with no possible interfaces listed and tracked it to the GLOBAL_CFG registers for different modes returning 0. A workaround has been added to the series. Unfortunately the HPG doesn't mention a proper way of doing it or even mention any such issue at all. Changes since v2: - add a patch that addresses an issue with GLOBAL_CFG registers returning 0 - reuse aqr113c_config_init() for aqr115c - improve commit messages, give more details on the 2500BASEX mode reuse Link to v2: https://lore.kernel.org/lkml/Zn4Nq1QvhjAUaogb@makrotopia.org/T/ Changes since v1: - split out the PHY patches into their own series - don't introduce new mode (OCSGMII) but use existing 2500BASEX instead - split the wait-for-FW patch into two: one renaming and exporting the relevant function and the second using it before checking the FW ID Link to v1: https://lore.kernel.org/linux-arm-kernel/20240619184550.34524-1-brgl@bgdev.pl/T/ ==================== Signed-off-by:

Add support for a new model to the Aquantia driver. This PHY supports 2.5 gigabit speeds. The PHY mode is referred to by the manufacturer as Overclocked SGMII (OCSGMII) but this actually is just 2500BASEX without in-band signalling so reuse the existing mode to avoid changing the uAPI.

When the PHY is first coming up (or resuming from suspend), it's possible that although the FW status shows as running, we still see zeroes in the GLOBAL_CFG set of registers and cannot determine available modes. Since all models support 10M, add a poll and wait the config to become available. Signed-off-by:

The driver triggers a "Secondary Bus Reset" (SBR) by calling __pci_reset_function_locked() which asserts the SBR bit in the "Bridge Control Register" in the configuration space of the upstream bridge for 2ms. This is done without locking the configuration space of the upstream bridge port, allowing user space to access it concurrently. Linux 6.11 will start warning about such unlocked resets [1][2]: pcieport 0000:00:01.0: unlocked secondary bus reset via: pci_reset_bus_function+0x51c/0x6a0 Avoid the warning and the concurrent access by locking the configuration space of the upstream bridge prior to the reset and unlocking it afterwards.

Commit 31a0fa00 ("thermal/debugfs: Pass cooling device state to thermal_debug_cdev_add()") changed the thermal core to read the current state of the cooling device as part of the cooling device's registration. This is incompatible with the current implementation of the cooling device operations in mlxsw, leading to initialization failure with errors such as: mlxsw_spectrum 0000:01:00.0: Failed to register cooling device mlxsw_spectrum 0000:01:00.0: cannot register bus device The reason for the failure is that when the get current state operation is invoked the driver tries to derive the index of the cooling device by walking a per thermal zone array and looking for the matching cooling device pointer. However, the pointer is returned from the registration function and therefore only set in the array after the registration. The issue was later fixed by commit 1af89ded ("thermal: core: Do not fail cdev registration because of invalid initial state") by not failing the registration of the cooling device if it cannot report a valid current state during registration, although drivers are responsible for ensuring that this will not happen. Therefore, make sure the driver is able to report a valid current state for the cooling device during registration by passing to the registration function a per cooling device private data that already has the cooling device index populated. While at it, call thermal_cooling_device_unregister() unconditionally since the function returns immediately if the cooling device pointer is NULL. Reviewed-by:

A forgotten or buggy variable initialization can cause out-of-bounds access to a register or other item array field. For an overflow, such access would mangle adjacent parts of the register payload. For an underflow, due to all variables being unsigned, the access would likely trample unrelated memory. Since neither is correct, replace these accesses with accesses at the index of 0, and warn about the issue. Suggested-by:

Some workloads may want to rehash the flows in response to an imbalance. Most effective way to do that is changing the RSS key. Check that changing the key does not cause link flaps or traffic disruption. Disrupting traffic for key update is not incorrect, but makes the key update unusable for rehashing under load.

Some devices dynamically increase and decrease the size of the RSS indirection table based on the number of enabled queues. When that happens driver must maintain the balance of entries (preferably duplicating the smaller table). Reviewed-by:
-
Jakub Kicinski authored
By default main RSS table should change to include all queues. When user sets a specific RSS config the driver should preserve it, even when queue count changes. Driver should refuse to deactivate queues used in the user-set RSS config. For additional contexts driver should still refuse to deactivate queues in use. Whether the contexts should get resized like context 0 when queue count increases is a bit unclear. I anticipate most drivers today don't do that. Since main use case for additional contexts is to set the indir table - it doesn't seem worthwhile to care about behavior of the default table too much. Don't test that. Reviewed-by:

Wrap up sending traffic and checking in which queues it landed in a helper. The method used for testing is to send a lot of iperf traffic and check which queues received the most packets. Those should be the queues where we expect iperf to land - either because we installed a filter for the port iperf uses, or we didn't and expect it to use context 0. Contexts get disjoint queue sets, but the main context (AKA context 0) may receive some background traffic (noise). Reviewed-by:

The basic test may fail without resetting the RSS indir table. Use the .exec() method to run cleanup early since we re-test with traffic that returning to default state works. While at it reformat the doc a tiny bit. Reviewed-by:

syzbot reported a UAF caused by a race when the L2TP work queue closes a tunnel at the same time as a userspace thread closes a session in that tunnel. Tunnel cleanup is handled by a work queue which iterates through the sessions contained within a tunnel, and closes them in turn. Meanwhile, a userspace thread may arbitrarily close a session via either netlink command or by closing the pppox socket in the case of l2tp_ppp. The race condition may occur when l2tp_tunnel_closeall walks the list of sessions in the tunnel and deletes each one. Currently this is implemented using list_for_each_safe, but because the list spinlock is dropped in the loop body it's possible for other threads to manipulate the list during list_for_each_safe's list walk. This can lead to the list iterator being corrupted, leading to list_for_each_safe spinning. One sequence of events which may lead to this is as follows: * A tunnel is created, containing two sessions A and B. * A thread closes the tunnel, triggering tunnel cleanup via the work queue. * l2tp_tunnel_closeall runs in the context of the work queue. It removes session A from the tunnel session list, then drops the list lock. At this point the list_for_each_safe temporary variable is pointing to the other session on the list, which is session B, and the list can be manipulated by other threads since the list lock has been released. * Userspace closes session B, which removes the session from its parent tunnel via l2tp_session_delete. Since l2tp_tunnel_closeall has released the tunnel list lock, l2tp_session_delete is able to call list_del_init on the session B list node. * Back on the work queue, l2tp_tunnel_closeall resumes execution and will now spin forever on the same list entry until the underlying session structure is freed, at which point UAF occurs. The solution is to iterate over the tunnel's session list using list_first_entry_not_null to avoid the possibility of the list iterator pointing at a list item which may be removed during the walk. Also, have l2tp_tunnel_closeall ref each session while it processes it to prevent another thread from freeing it. cpu1 cpu2 --- --- pppol2tp_release() spin_lock_bh(&tunnel->list_lock); for (;;) { session = list_first_entry_or_null(&tunnel->session_list, struct l2tp_session, list); if (!session) break; list_del_init(&session->list); spin_unlock_bh(&tunnel->list_lock); l2tp_session_delete(session); l2tp_session_delete(session); spin_lock_bh(&tunnel->list_lock); } spin_unlock_bh(&tunnel->list_lock); Calling l2tp_session_delete on the same session twice isn't a problem per-se, but if cpu2 manages to destruct the socket and unref the session to zero before cpu1 progresses then it would lead to UAF.

On sa8775p-ride-r3 the RX clocks from the AQR115C PHY are not available at the time of the DMA reset. We can however extract the RX clock from the internal SERDES block. Once the link is up, we can revert to the previous state. The AQR115C PHY doesn't support in-band signalling so we can count on getting the link up notification and safely reuse existing callbacks which are already used by another HW quirk workaround which enables the functional clock to avoid a DMA reset due to timeout. Only enable loopback on revision 3 of the board - check the phy_mode to make sure. Signed-off-by:
